A recent study suggests that patients who come off blockbuster weight-loss injections like Wegovy and Mounjaro can put back on reduced body mass far faster than those who stop conventional lifestyle regimens.
Published data in a prominent health publication shows that while overweight individuals often shed about a fifth of their total mass while undergoing treatment, the mass comes back at an average rate of 0.8 kg per month once they quit.
"Users buying such medications need to be informed of the danger of quick weight regain when the medication ends," stated researcher Dr. Susan Jebb.
Such speed of recovery means a return to pre-treatment mass within about 18 months.
Analyzing Approaches
The study, which reviewed 37 of studies involving over 9,000 of patients, contrasted the outcomes of these new drugs with conventional dieting.
Scientists point out that individuals who shed pounds through dieting usually experience a less rapid weight regain—perhaps 0.1 kg a month—after stopping.
Explaining the Rapid Rebound
Experts believe the mode of action of the drugs explains the accelerated rebound.
The injections imitate a natural hormone called GLP-1, which controls hunger.
"Artificially providing the hormone levels several times higher than the body's typical production might result in the body to generate a reduced amount of its own natural hormone, and could lessen responsiveness to its effects," explained Dr. Adam Collins, a dietetics researcher.
"Stopping of this hormone supplement results in hunger is uncontrolled, making binge eating much more probable."
An Ongoing Disease?
The NHS advise the jabs for individuals with weight-linked health risks, alongside prescribed diet and exercise modifications.
A number of clinicians contend that, given the high risk of relapse, the therapy should be considered life-long.
This view is echoed by pharmaceutical companies, who say that the results "emphasize the persistent nature of obesity," similar to managing conditions like high blood pressure.
User Experiences
Individuals who have discontinued the jabs describe a intense resurgence of cravings.
"It was like a trigger activating and you become ravenous," described one woman.
The struggle is worsened if patients have not adopted lasting lifestyle or habit modifications during treatment.
Growing Interest
Recent estimates show that a significant number of people in the UK have used weight-loss jabs in the past year, with interest continuing to grow.
- Use is more common among women compared to males.
- The 40s and 50s demographic shows the highest usage rates.
- Many obtain the medications through private prescriptions rather than the NHS.
In conclusion, clinicians caution that while the jabs are potent agents for weight loss, they are not a standalone fix and lasting health benefits relies on ongoing lifestyle changes.
